Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72284, here are decompositions:

7 + 72277 = 72284
13 + 72271 = 72284
31 + 72253 = 72284
61 + 72223 = 72284
73 + 72211 = 72284
181 + 72103 = 72284
193 + 72091 = 72284
211 + 72073 = 72284

Showing the first eight; more decompositions exist.
